Answer:

y^2

Step-by-step explanation:

One way of doing this problem is to multiply both numerator and denominator by y^7. Doing this we get:

y^(-2+7)

--------------- = y^2

y^(-7+7)

Answer:

y^5

Step-by-step explanation:

y^-2/y^-7

When we divide exponents with the same base, we subtract the exponents

y^ ( -2 - -7)

y^ ( -2+7)

y^ 5

| 2 +r | ≥ 3 (lines are absolute value)

Alex777 [14]

Answer:

r ≤ -5 and r ≥ 1

Step-by-step explanation:

The solution has two parts:

1) that derived from | 2 +r | ≥ 3 when (2 + r) is already positive. Then:

2 + r ≥ 3, or r ≥ 1

and

that derived from | 2 +r | ≥ 3 when (2 + r) is negative. If (2 + r) is negative, then

|(2 + r)| = -(2 + r) = -2 -r, which is ≥ 3. Therefore, -2 -r ≥ 3, or -r ≥ 5. To solve this for r, divide both sides by -1 and reverse the direction of the inequality sign: r ≤ -5

How many numbers between 1 and 100 are multiples of both 2 and 7

liraira [26]

7. The formula is : $98-14=84$ and then $\frac{84}{14}$ and then $6+1=7$ .

The reason behind it is 14 is the least common multiple of 7 and 2 and 98 is the largest 2 digit multiple of 14. Subtract 98 and 14 and then divide by 14 to get 6 and then add 1. You will get 7 which is our answer!
